Automatic optimization techniques have been used in recent years for the aerodynamic and mechanical design of turbomachinery components. Despite the many advantages, their use is usually limited to simple applications in industrial practice, because of their high computational cost. In this paper, an optimization strategy is presented, which enables the three-dimensional multipoint, multi objective aerodynamic optimization of turbomachinery blades in a time frame compatible with industrial standards.
The design strategy is based on the coupling of three-dimensional inverse design, response surface method, multiobjective evolutionary algorithms, and computational fluid dynamics analyses.
